Brooks Review, Is Brooks Non-Toxic?
Brooks averages 51 out of 100 on PFAS Authority's PFAS and toxin screen across the 22 Brooks products graded as of November 2026, and none of them reach its 70 point pass mark.
Brooks grades Good on our four-band scale. On disclosure, the brand says nothing publicly about PFAS. See what every brand has published about PFAS for how that compares.
PFAS Authority is a scoring system, not a laboratory. We do not test products ourselves. Grades are model-based, built from published ingredients, materials, certifications, brand disclosures and third-party lab results where they exist. See the rubric.
